There is a discussion about improving the usability of kselftest by creating test-specific kconfig in recent kernel Summit. The first three versions could be found at [1], [2], [3]. Patch 1 keep test-specific kconfig fragments inside each selftest so that merge_configs.sh could build up a kernel configuration that can test the specific or all feature(s). Patch 2 add config option(kselftest-merge) in make file as a helper to merge all the test config dependecies to .config. Changes since v3: 1. move the target kselftest-mergeconfig from scripts/kconfig/Makfile to toplevel Makefile. And rename to kselftest-merge to avoid the conflict with "%config" target. Changes since v2: 1. Fix the misuse of objtree and srctree in the kselftest-mergeconfig target. Changes since v1: 1. Add kselftest-mergeconfig in scripts/kconfig/Makefile according to the suggestion from Michael.
